Benefits of technology

The invention is a fibrous sheet material printing pre-treatment apparatus and method that includes a conveyor belt and an adhesive applicator for fixing the fibrous sheet material to the conveyor belt. The conveyor belt has a closed path and the adhesive applicator applies adhesive to the conveyor belt or the fibrous sheet material. The apparatus also includes a drying station with an inlet and outlet for directing airflow on the fibrous sheet material during passage through bends in the conveyor belt. The method includes moving the conveyor belt and fixing the fibrous sheet material to the conveyor belt, at least partially drying the fibrous sheet material, and then withdrawing it from the conveyor belt. The technical effects of the invention include improved printing quality, reduced paper waste, and efficient production.

Problems solved by technology

In digital printing, jet heads having a plurality of nozzles with small ink passage opening are used, and it is virtually impossible to directly add additive to the ink because the ink could become much too viscous, which would prevent controlling the ink passage through the heads, or could develop chemical or physical properties that are not easily manageable by the systems controlling the digital print heads.

Embodiment Construction

[0049]Reference 1 generally indicates an apparatus for treating a fibrous material T having a sheet shape and destined to be printed, for example by digital printing. The apparatus 1 is useable for treating a sheet fibrous material, for example consisting of or comprising a fabric and / or a non-woven fabric, before an ink-printing process on at least one side of said sheet. Generally but in a non-limiting way, the apparatus 1 can be useful in the textile or knitted fabric or non-woven fabric industry for preparing a material to be ink-printed.

[0050]As is visible in FIG. 4, apparatus 1 comprises at least one conveyor belt 2 movable along a closed path, particularly between at least one first and one second terminal idler members 3, 4 along a predetermined advancement direction A. The conveyor belt 2 has a structure having two dimensions: length and width, substantially prevalent with respect to a third dimension, such as the thickness; the length is defined along the belt 2 advancemen...

Abstract

An apparatus and method for treating a sheet fibrous material to be printed with ink. The apparatus includes a conveyor belt movable along a closed path including an operative section defining a plurality of bends, an inlet station that receives the sheet fibrous material and adheres a first side of the material to an exposed surface of the conveyor belt, a drying station placed at the operative section and configured to at least partially dry the sheet fibrous material, and an applicator for applying a wet treatment agent to the material prior to drying.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of and claims priority to PCT Application Serial No. PCT / IB2016 / 051301, filed on Mar. 8, 2016, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention refers to an apparatus and associated process for treating a sheet-form fibrous material, such as a fabric and / or a non-woven fabric, destined to print, for example digital print. The invention can be applied in the textile industry for preparing knitted, woven or non-woven fabrics for printing, for example by digital-type printing.BACKGROUND[0003]Conventional printing—in other words, using cylinders or printing silk-screen frames—and digital-type printing—in other words, using one or more nozzle printing heads—are technologies used for applying inks or paints defining motifs, patterns, colorations on different types of sheet materials such as, for example, paper, fabrics, non-woven fabrics, felt,...
